Pathetic service

After waiting a whole year for someone to come out and give me a quote I then have to run after him to get an invoice so I can make payment as soon as I recieved the invoice I made full payment. As discussed at the time of giving us the quote that the gate will be installed on friday 11th Dec at 2pm. After payment was made no1 got back to us with any feed back. I've had to call in so many times and all I heard was they will call back and that never actually happend. Then kyle emails me to say that the stock isn't there and the delay was coz payment was made late. *** how is that my fault. I'm leaving to india on Tuesday therefore I went ahead with wat was discussed thinking they will stay true to their word but I was wrong I'm disgusted
